摘要
提出了一种求解带副翼偏转三维机翼绕流的 Euler方程计算方法。采用对接分区网格与分区求解算法的结合,有效地求解绕此外形的复杂流动。提出了一种满足通量守恒的内边界耦合条件。数值方法中选用 Van Leer 分裂格式离散无粘通量项,并构造了一种 Lim iter函数以保证 T V D 性质。数值算例表明本方法是求解带操纵面偏转的机翼绕流的有效方法。
An Euler method for solving the flow around a wing with deflection of control surface(aileron) is presented.Using the combination of patched grid and domain decomposition techniques,the complex flow around this kind of configuration is effectively solved.An internal coupling condition satisfied the conservation of flux is given.In the computation Van Leers schcme is used to discretize the inviscid flux terms and a new limiter function is constructed to realize TVD character.Numerical results show that the present method is effective one for solving the flow around wing with control surface deflection.
